SFP450-12BG Datasheet | Power-One

SFP450-12BG AC-DC Front-End Data Sheet 12V Output, 450 Watts Features - Ro HS pliant for all six substances - Wide input voltage range (90-264 VAC) with PFC High power density, 9 Watts/cubic inch 1U or 2U height configurations Active current share with ORing FET I2C interface status and control Standby voltage of 3.3 VDC @ 3 A Overtemperature, overload, and overvoltage protection - Status LEDs: AC OK, DC OK, Overtemperature .. - - - - - - Applications - Data - Distributed power systems Description The SFP450-12BG is a 450-watt, power factor corrected (PFC) front-end which provides a 12 VDC output for data and other distributed power applications. Its pact size enables mounting in both 1U and 2U height racks. High efficiencies, advanced thermal management techniques, and an internal fan increase reliability over a broad range of operating conditions. Internal ORing diodes facilitate use in hot-swap, redundant configurations. Status is provided with front panel LEDs, logic signals, and via the I2C management interface bus. In addition, the I2C bus can enable the power supply and control fan speed. The SFP450-12BG meets international safety requirements and is CE marked to the Low Voltage Directive (LVD).
